查询词典 decreases

It uses nanoscale materials to boost the performance of its batteries (making an electrode out of nanoparticles increases its surface area, which in turn decreases the battery's internal resistance and improves its ability to store and deliver energy). Its batteries are already used in power tools, and the company has formed alliances to supply Chrysler and SAIC Motor Corporation of Shanghai with car-sized versions.

它的方法是利用纳米尺寸的材料来提升电池的性能（电极周围是纳米粒子，这增大了表面积，反过来使电池内部阻力降低，因此提高了容量），其产品已经应用于某些动力设备。A123与克莱斯勒和上汽集团合作，为他们提供汽车所需尺寸的电池。

Not only does it keep your costs high, it also decreases customer loyalty and increases customer churn.

这不仅让你的成本高涨，同时也会减少客人的忠诚度、增加客户的混乱程度。

However, because of the limitation by circular orbit, we can't obtain all the data in Radon Space which means that the result becomes better with the cone angle decreases. So it is important to study the relationship between the cone angle and the reconstruct quality further.

但是由于圆轨道几何结构的限制，使其不能够得到完备的锥束重建数据，只有在锥角较小的情况下才能得到，因此深入研究Radon空间的数据缺失与锥角的关系以改进算法。

In the case of adding citric acid, the specific surface area of the products decreases with the increase of n/n.

在加入柠檬酸的情况下，产物的比表面积随n/n增加而减小。

7Gm〓 in the 20 yr forest, 1139. 8gm〓 in the 80 yr forest and 912. 4 gm〓 in the climax forest, respectively. However, along with forest succession, the dominant tree species fine root annual production increases, whereas other arboreal and grass fine root annual production decreases.

白桦山杨幼林、白桦山杨成熟林与原始阔叶红松林中，细根年生长量分别为712.7gm〓、1139.8gm〓和912.4gm〓；但是，随着演替的进行，林地主要树种细根的年生产量会逐渐增加，其它木本和草本细根的年生产量则逐渐降低。

The fcc structure is a close-packed structure, and the bcc structure is not, which explains why the volume of the iron decreases when this transformation occurs.

由于面心立方结构是一种密堆垛结构，而体心立方则较松散，这解释了铁在加热过912℃后体积减小的现象。

And VTMS is added in late stage of polymerization, in this situation the system has the lowest coagulum. When the hydroxyl value of such polymer increases, the coagulum decreases; and solid content of such polymer increases, the coagulum increases greatly, so it is difficult to get higher solid content emulsion.

采用正交实验方法，通过对有机硅改性丙烯酸乳液聚合过程中凝聚物含量、乳液粘度影响的研究，确定的最佳的反应条件是：以SLS/OP为乳化剂、比例为4/6、用量为2％、丙烯酸单体的用量1.5％、反应温度为75℃、改性剂VTMS用量是1.5％、改性剂后加入方式下聚合反应过程中有最低的凝聚物含量。

More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点，首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合，发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大，具有单分散性；较多的纳米粒子导致较大的乳液粒径；反应温度升高，凝聚物含量下降，而乳液粘度和乳胶粒粒径增加，在相同的反应温度下，纳米粒子降低了聚合过程中的凝聚物含量，增加了乳液聚合物的粘度和粒径；不论纳米粒子是否存在，当无皂乳液核组成中亲水单体AA和HEMA用量增加时，乳胶粒粒径均减少。

The humic acid content of lignite varies in a wide range of from 3.3 to 67.8%; it decreases sharply with increasing degree of coalification.

褐煤腐植酸含量变动较大，在3.3—67.8%；随着煤化程度增加，腐植酸量有明显减少的趋势。

After 25% deformation at 850℃, and relaxation for 6 to 30 seconds, a great deal of fine Nb particles precipitates in steels, the size of particles is less than 10nm. With the increase of relaxation time, the amount of precipitates starts to decreases, the size coarsen to greater than 10nm.

在850℃变形后随驰豫时间的延长，在6～30秒内有大量细小的Nb粒子应变诱导析出，其尺寸小于10nm，驰豫时间再进一步延长，析出数量开始减少，粒子的尺寸粗化为10nm以上。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.

你一定是病了，你的脸色苍白。
